How much free space do you have on the drive that holds the session 
data?  I don't think there is an arbitrary limit on session size.  Just the 
limitations of the resources of your machine.


This thread probably belongs on php-general.  This list is for the 
development _of_ php, not _with_ php.

What I have that you do not:
   cli - create command line interface executable program.
   calendar - fancy tricks with dates.
   pear - a library of handy functions
   gd-native-ttf
   pdflib - create pdf files
   ming - create swf files
   magic-quotes - eliminates a lot of addslashes()
   mm - I'm not sure
   pspell - spelling checker

I don't think anything I added would make any difference.

Things that look wrong to me:

--with-low-memory, --with-elf and --with-x are not listed as valid options 
in ./configure --help, and look scary to me.  Get rid of them.


You used enable-zlib, but the correct statement is with-zlib or with-zlib-dir.


--enable-track-vars - is enabled by default and ignored for a couple of php 
versions now.

--enable-versioning - is only needed when you want to run more than one PHP 
module version at the same time.



The next thing to try...

xpm-dir, bz2, imap, iconv  are the modules you are using that I am 
not.  Try compiling without them and see what happens.



I don't see where any of these _should_ affect things, but I've gotten in 
trouble before using options I did not need...

--prefix - --with-apache specifies where the resulting files are placed, so 
prefix is not relevant to static install.

localstatedir, infodir, mandir - not relevant to a static install because a 
php module does not use any of the directories specified by these.

I have a site in wich user can register, but everyone can navigate as
Guest, even if he/she is nt registered.
The problem is that I need session for registered user, but I don't
need them for unregistered ones!
So I tried to check if they already have an opened session (they are
registered), but to check it I have to do a session_start(), and this
will OPEN a session if it's not opened! So I'll have an opened session
for every guest I have in the site. This is difficult for me because I
would like session to last very long, and many empty session waste a
lot of space!


Try something like:

if( isset( $REQUEST[ 'PHPSESSID' ] )) { #  User is registered/logged in
   session_start();
   }

This is based on looking for the cookie or get value for PHPSESSID, the 
default session name.  If it is set, then either a cookie with the session 
ID is set, or the session is being passed in the URL.

[PHP-DEV] is_callable documentation

I just submitted documentation for the is_callable function.  I _think_ is 
correct, but someone who knows more about it than I might want to look it 
over.  It should appear soon in the user notes at:

Thanks to Andrei Zmievski and leon  leonatkinson.com for the

I personally dissagree here - an error is a bit harsh if it doesn't hinder
execution - I dont see anything in getimagesize() which should return
E_ERROR - only E_NOTICE if the file is corrupt, unless I'm missing
something.


If you don't want to see the filesystem error use @ to hide them.  Having 
filesystem errors available makes troubleshooting easier.  If GetImageSize 
never returns them, how do you figure out what is wrong when you it returns 
false?

Re: [PHP-DEV] Default Return-Path with mail() and qmail

I'm a big -1 on this.  The patch will not actually solve the root problem.

On Unix systems, the MTA needs to know that the webserver user is
'trusted' to masquerade as another user.  In exim this would be the
'trusted-users' directive, sendmail, qmail, and postfix have similar
directives.

I agree that the documentation could use some updating in this regard and
would be happy to make that modification after I collect up some examples
of the correct directives to use on common systems.


Qmail seems to trust everyone on the system by default.  I did nothing 
special to allow 'nobody' rights to use sendmail -f to set the From: 
address.  (Running Qmail's sendmail wrapper.)


You might consider recommending a configuration setting like the following 
in each  block on a multi-domain Apache server.  This sends 
bounces and replies to the webmaster of the domain if no attempt is made to 
set the From: and Reply-to: headers when mail() is used.


pph_admin_value sendmail_path "/usr/sbin/sendmail -t [EMAIL PROTECTED]"



I think sendmail requires the user to be a member of the 'trusted' group, 
but I yield to anyone who knows more about it.

May I suggest the best choice is to fix the code.  The current action is

A to Z followed by AA - AZ, BA - BZ ... up to YA-YZ, then if finally

If that isn't bad enough for you, try the range from A to z.  After 30

Hello,

In what situations will memory allocated to a script remain with the

I always thought that memory allocated would be released on script

Could it be that the heap in the apache process stays at the maximally
used level ?


My understanding is that once an Apache process increases its stack space, 
that stack space stays allocated until the process dies.  For a short term 
fix lower the MaxRequestsPerChild so the big stack processes die off 
sooner.  Long term fix is to upgrade the script causing the problem, 
assuming it has actually been fixed per Marcus' message.

If there are only a few, kill them off by hand.  Apache will start a new one.

No,  but since no one has given any reason why line numbers should not

A little of both.  There seem to be some here who thing their style of

is the only valid one and have no tolerance for the choices of 
others.  Most people
here are great, and PHP is a fantastic language because of it.

I haven't seen any reason not to include it, other than a suggestion that .phps
should never be used, so it does not need to be improved.  Anyone is free to
disable .phps on their system and ignore it.  The rest of us seem to like the
idea.  Please get it over with.  Install the patch.

I agree!  Has ANYONE given a good reason why .phps should not ALWAYS have
line numbers turned on.  ?HIGHLIGHT_FORMAT  is a hassle and likeley to be
forgotten when you need it most.  People who don't use .phps have no business
in making this decision.  You are free to disable it on your system and

Re: [PHP-DEV] highlight_file modification

[Rick Widmer]

May I suggest that for .phps you just turn line numbers on all the time,
unless someone can come up with a reason not to enable them better
than "that's the way its always been."   Backwards compatibility is good
when it affects how a program runs, but in this case I just don't see a
reason not to enable line numbers.

My guess is the most common, if not the _only_ use for .phps is
displaying php source code for humans to read.  Maybe if you can find
more than one person who is pulling .phps output into a program and
parsing it then _maybe_ that might be a reason not  to turn on line
numbers all the time.

Considering the number of people the line numbers will help, I'm not sure
finding just one or two people who expect no line numbers is reason
enough not to turn it on all the time.  Like it is _so_ hard to just ignore
(or remove) them if you don't need them.

What part of "YOU  CAN'T RELY ON IP ADDRESSES FOR AUTHENTICATION!!!"
don't you understand?  IT DOES NOT WORK!  PERIOD... EVER, at least on the
real Internet world!

I've seen a page request, and the images on that page come from different IP
addresses in the AOL block of addresses.  I know they came from the same
browser, yet they show different IP addresses. AOL is not the only place that
proxies/caches traffic from their users.  You can't trust IP addresses to match
with the browser they came from, not even within one single page load.
